i just purchased a greddy evo exhaust for my 03 civic si. inside the box it has 1 gasket in it. does that gasket go inbetween the muffler and exhaust pipping(located where the rear axel is) or does it go at the very end of the exhaust( in the location of where the cat is located)? thanks for your help.

 

i'm pretty sure it goes after teh cat. converter..but place it in both spots and see which fits best
